What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked back at records of 67 children to see if a broken front tooth from an injury could lead to hidden changes in the jaw joint. Researchers used special 3D X-rays (CBCT) to measure joint spaces and check for pain. They found that children with tooth fractures had different joint measurements compared to those without fractures, even if they didn't feel pain. The goal was to better understand these hidden changes, not to test a new treatment.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Single-center pediatric cohort drawn from dental trauma cases (presenting ≤1 month post-injury) and orthodontic records (Class I, asymptomatic) at a university clinic; retrospective review period 2008-2023. TMJ joint-space metrics via CBCT (Ikeda \& Kawamura method); pain scored on a 4-point ordinal scale; ALADA principles applied; no additional radiation for research.

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Children/adolescents aged 11-16 years. * Cases: History of complicated crown-root fracture due to dental trauma; presentation within 1 month after trauma; documented TMJ pain (palpation and/or movement); CBCT available for TMJ assessment. * Controls: Orthodontic patients (Class I) aged 12-16 years with no TMJ-related complaints; pre-treatment CBCT available. * Availability of standardized clinical records (pain side/intensity; mandibular movement) sufficient for retrospective analysis. * Parental/guardian consent obtained at initial treatment per institutional policy. Exclusion Criteria: * Systemic/rheumatologic or neuromuscular disorders affecting the TMJ (e.g., JIA). * Craniofacial syndromes, prior TMJ surgery, mandibular fractures involving the condyle, or forced/intubation trauma unrelated to dental injury. * Prior or ongoing occlusal splint/orthodontic therapy likely to alter TMJ loading before baseline imaging. * Inadequate/incomplete clinical records or poor-quality CBCT precluding reliable joint-space measurement. * Repeated or multiple traumas where timing cannot be ascertained relative to imaging.
